  • DETECTING AND ESTIMATING ANISOTROPY ERRORS USING FULL WAVEFORM INVERSION AND RAY BASED TOMOGRAPHY
    Publication number: 20160187512
    Abstract: Anisotropy errors in seismic velocity data for a geophysical structure are detecting by obtaining seismic data for the geophysical structure, using conventional ray-based tomography to generate an initial model of the geophysical structure, the initial model containing initial values for Thomsen parameters velocity along an axis of symmetry, epsilon and delta, using a first inversion process preferably transmission-based full waveform inversion of the seismic data to obtain updated values for epsilon and using a second inversion process preferably ray-based reflection tomography of the seismic data to obtain updated values for velocity along the axis of symmetry.
